Title: Image reader
Inventor: NAGAMINE KENJI
IPC: H04N1/19
Filed: 1985-02-06
Abstract: PURPOSE:To obtain a stable image reading output without read error by allowing a constant current control section to apply constant current control to a light source current of a light source array section so as to eliminate a change in luminous amount of the light source. CONSTITUTION:An original 2 placed on an original platen 1 is lighted by a light source array section 3 comprising plural light emitting elements. The reflected light including image information from the original is collected by a lens of a lens section 10 and converted into an electric signal according to the reading of a linear image sensor section 7 comprising plural photoelectric converting elements in the main scanning direction. The reading in the main scanning direction of the image sensor section 7 and a light source switching section 4 are synchronized to blink sequentially the light sources of the light source array section 3 and a constant current control section 5 applies constant current control to the light source current. Thus, the current consumption and heat of the light source are reduced and the luminous amount of the light source array 3 is made constant.

Title: Bistable multivibrator
Inventor: SUZUKI TOSHIYASU
IPC: H03K3/29
Filed: 1988-02-02
Abstract: PURPOSE:To reduce the number of parts used for a bistable multivibrator and to make the difference in the output voltages of the two stable states of the multivibrator larger by constituting the multivibrator by connecting two transistors, two resistances, and two sets of DC power sources by means of a specific circuit. CONSTITUTION:When a transistor 4 is turned on, a loop containing a DC power source 2, the emitter connection of the transistor 4, and a resistance 6 is formed and another transistor 3 is turned off. In this state, the transistor 4 draws the base potential of the transistor 3 to the earth potential and fixes the base potential. The potential at a terminal t1 is lower than the earth potential by the emitter junction voltage of the transistor 4 and is negative. When the transistor 4 is turned off, on the other hand, the transistor 3 is turned on and a DC power source 1 impresses a reverse voltage across the emitter junction of the transistor 4. In this state, the transistor 3 draws the emitter potential of the transistor 4 in the positive direction and fixes the emitter potential. The potential at the terminal t1 becomes almost equal to the potential at the positive terminal of the DC power source 1 if the ratio between the resistance values of the resistances 5 and 6 is selected.

Title: Circuit for discriminating logic of video synchronizing signal
Inventor: AOKI NOBUAKI
IPC: G09G5/12
Filed: 1988-02-02
Abstract: PURPOSE:To obtain video synchronizing signal outputs having fixed output synchronizing signal logic by fetching the signal voltage level during a nonactive period by means of an RC smoothing circuit and using the fetched level and original signals as the two inputs of an exclusive OR circuit. CONSTITUTION:Assuming that synchronizing signals which become 'H' during the 5% period of a pulse period are inputted, one input terminal 3b of an exclusive OR circuit 3 becomes almost equal of the 'L' which is the level during the 95% period of the pulse period by means of the RCLPF of a smoothing circuit 6. When the input terminal 3b is 'L', the circuit 3 functions as a buffer and the input of the other input terminal 3a of the circuit 3 is inverted by an inverter 2. Therefore, the output signal 5 of the circuit 3 becomes active 'L' of the logic inverted from the logic of the input signal. When synchronizing signals which becomes 'L' during the 5% period of the pulse period thereafter, the input terminal 3b of the circuit 3 becomes almost equal to 'H' which is the level of the 95% period of the pulse period by means of the circuit 6. When the input terminal 3b is 'H', the circuit 3 functions as an inverter and the output signal 5 becomes active 'L' of the same logic as that of the input signal.

Title: Piezoelectric element, and actuator and ink jet recording head using the same
Inventor: NISHIWAKI MANABU
IPC: B41J2/135
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To improve the property of withstand voltage of a piezoelectric element by a method wherein a low-dielectric substance having a lower dielectric constant than the one of a piezoelectric film is formed in the region of the piezoelectric film wherein grain boundaries are exposed. SOLUTION: A piezoelectric film 12 is formed on a lower electrode 11, and a low- dielectric substance 14 having a lower dielectric constant than the one of the piezoelectric film 12 is formed on the piezoelectric film 12, in the region of this film 12 wherein grain boundaries are exposed and in the vicinity thereof. Moreover, an upper electrode 13 is formed on the piezoelectric film 12 whereon the low-dielectric substance 14 is formed. When an electric field is impressed on a piezoelectric element 10 formed in this way, accordingly, a voltage applied to the grain boundaries of the piezoelectric film 12 can be made lower than the one in the case when the low-dielectric substance 14 is not formed, due to the existence of the low-dielectric substance 14 formed in the region of the piezoelectric film 12 wherein the grain boundaries are exposed, at least.  Since a leakage current flowing through the grain boundaries of the piezoelectric film 12 can be reduced, in other words, occurrence of a dielectric breakdown of the piezoelectric film 12 can be prevented. Thereby the property of withstand voltage of the piezoelectric element can be improved.
